Standard methods and means of testing are discussed, together with methods newly developed and tested by the authors. Various parameters, such as straightness, perpendicularity, flatness, pitch, yaw, roll, and so on, are introduced and the principal processes for measurement of these parameters are explained. Lists and tables of geometrical accuracy parameters, together with diagrams of arrangements for their control and evaluation of measurement results, are added. Special methods and some original new devices for measurement and monitoring are also presented. Information measuring systems, consisting of laser interferometers, photoelectric raster encoders or scales, and so on, are discussed and methods for the measurement and testing of circular scales, length scales, and encoders are included. Particular attention is given to the analysis of ISO written standards of accuracy control, terms and definitions, and methods for evaluation of the measurement results during performance verification. Methods for measuring small lengths, gaps, and distances between two surfaces are also presented. The resolution of measurement remains very high, at least within the range 0.05 [mu]m to 0.005 [mu]m. 410 0$aAutomation and control engineering. 606 $aMetrology 606 $aElectric machinery$xMonitoring 608 $aElectronic books. 615 0$aMetrology. 615 0$aElectric machinery$xMonitoring. 676 $a389.1015195 700 $aGiniotis$b Vytautas$0963583 702 $aHope$b Anthony 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910464314003321 996 $aMeasurement and monitoring$92184831 997 $aUNINA LEADER 02023nam 2200637Ia 450 001 9910784623403321 005 20221108042300.0 010 $a0-299-13933-6 010 $a9786612622823 010 $a1-282-62282-X 024 7 $a2027/heb02563 035 $a(CKB)1000000000396262 035 $a(dli)HEB02563 035 $a(SSID)ssj0000084586 035 $a(PQKBManifestationID)11112557 035 $a(PQKBTitleCode)TC0000084586 035 $a(PQKBWorkID)10169642 035 $a(PQKB)11519832 035 $a(MiAaPQ)EBC3445006 035 $a(OCoLC)317459978 035 $a(MdBmJHUP)muse12443 035 $a(Au-PeEL)EBL3445006 035 $a(CaPaEBR)ebr10394935 035 $a(CaONFJC)MIL262282 035 $a(OCoLC)927483756 035 $a(MiU)MIU01000000000000005053733 035 $a(EXLCZ)991000000000396262 100 $a19930216d1993 uy 0 101 0 $aeng 135 $aurmnummmmuuuu 181 $ctxt 182 $cc 183 $acr 200 10$aNo condition is permanent$b[electronic resource] $ethe social dynamics of agrarian change in sub-Saharan Africa /$fSara Berry 210 $aMadison, Wis. $cUniversity of Wisconsin Press$dc1993 215 $a1 online resource (xiv, 258 p. ) $cill., maps ; 300 $aBibliographic Level Mode of Issuance: Monograph 311 $a0-299-13934-4 311 $a0-299-13930-1 320 $aIncludes bibliographical references and index. 410 0$aACLS Humanities E-Book. 606 $aAgriculture and state$zAfrica, Sub-Saharan 606 $aAgriculture$xEconomic aspects$zAfrica, Sub-Saharan 606 $aRural development$zAfrica, Sub-Saharan 615 0$aAgriculture and state 615 0$aAgriculture$xEconomic aspects 615 0$aRural development 676 $a338.1/0967 700 $aBerry$b Sara$0918602 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910784623403321 996 $aNo condition is permanent$92059948 997 $aUNINA
